A 700 MHz bandwidth guided wave acoustooptic Bragg cell was developed for use in an integrated optic spectrum analyzer. Various configurations of multiple tilted SAW transducers were investigated theoretically and experimentally to find the most efficient combination which would provide a 700 MHz sub-octave acoustooptic bandwidth. Investigated were Bragg cells fabricated on Ti diffused LiNbO3 waveguides as well as Ti diffused LiNbO3 waveguides with Nb2O5 thin film overlays. A Bragg cell consisting of 6 tilted transducers was designed, fabricated, and tested, exhibiting 700 MHz bandwidth and 2.8%/RF watt diffraction efficiency. The Bragg cell operates between 775 MHz and 1475 MHz. Projections are made on the performance of an integrated optic spectrum analyzer utilizing this Bragg cell based on results obtained from an existing 200 MHz bandwidth spectrum analyzer.
